At high pressures and temperatures in the vicinity of 1,000 DEG C., palladium, phosphorus and a chalcogen, X, which can be S or Se combine to form compounds having the formula PdPyX2-y in which y is 0.67 when X is S and y is 0.4 to 0.8 when X is Se and which have a pyrite-type crystal structure. The compounds PdPyX2-y are electrical conductors with an essentially zero temperature coefficient of resistance from liquid helium temperature to room temperature. The compounds are useful as electrical resistors.
